3 Claims.

My invention relates to .pipe hangers and to a building construction'embodying a pipe hanger. Y More particularly, it relates to pipe hangers for supporting cooling pipes in hardening or refrigerating rooms. V

In hardening or refrigerating rooms,l difficulties arise in supporting the pipes which carry the cooling medium. It has been found that the ceilings .of refrigerating rooms are likely to deteriorate very rapidly when in use. The cause of this troublesome defect is that the ceiling is subjected to extremes of temperature through the conduction of cold by the pipe supporting members. This is particularly true where the room above'the hardening room is one in which high temperatures are present. The material of which the floor:- of the room above is made, being constantly heated and cooled, is likely. to suier serious damage. This is particularly true where metallic beams are used 'n to support the hangers on which the cooling pipes frosted periodically. The coolness of the pipe' supporting rods causescondensation in the ceiling structure. When the room is defrosted, this frozen condensation thaws out and -is likely to cause serious inconvenience and to harm the ceiling construction. When it is refrozen, still further damage mayy occur.

A further disadvantage resides in the fact that heat is often conducted into the hardening room through the supports for the cooling pipes which thus lowers the eiiiciency of the room.

The principal object of my invention is to provide a pipe support and ceiling construction for hardening rooms in which the above disadvantages will not be present. Primarily, it is desirable to support the pipe hanger out of contact with the ceiling, particularly if this ceiling be of concrete, and out of contact with the beams by which the hanger is supported. This will avoid the chilling of the ceiling material'and will prevent any` condensation which might form on the rod from damaging the ceiling. Secondly, the construction will prevent the conduction of heat into the refrigerating room.

A further object is to support pipes in a relatively insulated condition without decreasing the strength or firmness of the supporting means.

In addition, my invention provides means for securing a pipe supporting rod immovably to a beam yet without any direct contact with the beam.

A nal purpose is to support the upperend of a pipe carrying rod securely while insulating such upper end both from the supporting beams and from the surrounding medium.

More speciiically, my object is to provide pipe holding means extendingV through the ceiling of a refrigerating room hanging from a reinforcing so beam in such ceiling but spaced from the beam by insulating material. In this respect, it is important that a part of the pipe holding means be above and vertically aligned with a part of the Vbeam so that the intervening relatively weak insulating material will not be subjected to shearing action. Further, it is advantageous to have positive means for spacing the rod laterally from the beam.

Other objects and advantages of my invention 7o. will appear more fully from the following description when taken in conjunction with the accompanying drawings which form a part thereof.

In the drawings:

Fig. 1 is a vertical cross section through one 75 form of the invention.

Fig.A 2 is a top plan view of thesame.

Figs. 3 and'4 are cross sections through modified forms of the invention.

Y The usual hardening room includes a concrete 30 Aceiling reinforced by steelbeams or girders and a cork layer bonded to the lower side of the concrete.

In Fig. 1, the beams 2 serve as supports or rein, forcements for a concrete ceiling 4 in which the 85 beams are cast. A mass of cork 6 is bonded or cemented to the lower face of the concrete to insulate the room. A finishing layer 8 of suitable plastic material may be applied to the cork. Pipes 10 serve to conduct cooling fluid into and 90 around the room and thus cool the room.

In order to support the pipes 10, I provide a cross beam 12 mounted between the beams 2 with its principal surface 14 arranged horizontally. This beam is provided at suitable intervals with openings 16.

A rod 18 is. provided extending from within the room through the cork 6 and the opening 16. The lower end of this rod is provided with suitable means 20 for supporting pipes threaded 100 thereon. The upper end of the rod is threaded, and a nut 22 engages the threaded portion. Below this nut is arranged a metal plate or disc 24 having a diameter greater than that of the opening 16 so that the disc partially overlies the hori- 105 zontal portion 14 of the beam 12. Between the disc 24 and the beam 12 and surrounding the rod 18 is a disc 26 of cork or other insulating material preferably larger in diameter than the disc 24. A further disc 28 is provided around the rod H0 18 within and filling the opening 16, thereby preventing lateral movement of the rod and eflectively insulating the same from the beam 12. The space between the beams 2 above and below the beam 12 is filled by large blocks 30, 32 of cork or other insulating material, thereby insulating the rod 18 even from the concrete 4.l

Fig.,3 shows a modied form of ceiling in which no concrete is used. In this form, the cork ceiling is supported by staples 40 having their lower ends bent at an angle as at 42. The bends of these staples are engaged by hooks 44 on theends of a rod 46 which extends across the top of and is supported by the beams 2. Otherwise this d form of the invention is not diierent from that shown in Fig. l. l

Fig. 4 shows a second method of supporting a ceiling of the type shown in Fig. 3. In this modification, a plate or bar 50 rests on top 4of the beams 2. Each end of this plate supports one end of a bent bar 52 which extends into the cork 6 to support the same. Y

It will be noted that in each fof 'the forms shown the rod 18 is insulated not only from the metallic supporting beams but also from the surrounding medium, whether it be air orconcrete. It will also-be evident that the disc 26 is not subjectto shearing forces, and lthat there is a positivev supporting action between the beam 12` and the disc 24 so that the pipes at no pointdepend on the tensile strength of insulating material for their support.- It is plain that the rod 18 will not conduct cold' from the refrigerating room into the ceiling or at least into the metallic and concrete parts of the ceiling structure. Chilling otthese parts and damage to them by condensation is thus avoided. Additionally, no heat will be conducted through the rod 18 into the refrigerating room.

While I have described herein some embodiments of my invention, I wish -it to be understood that I do not intend to limit myself thereby except within the scope of the appended/claims. l
